THOMAS CHATTE RTON, OF CLEVELAND, OHIO.

Letters Patent No. 67,496, dated August 6, 1867.

IMPROVEMENT IN STEAM ENGINE OIL-CUPS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, THOMAS CHATTERTON, of Cleveland, is the county of Cuyahoga, and State of Ohio, have invented certeinnew and useful Improvements in Oil-Cups; and I do hereby declare that the following is a full and complete description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view of the cup.

Figure 2, adetached section.

Figure 3, a vertical transverse section.

Figure 4, a detached section.

Like letters of reference refer to like parts in the diflerent views.

A, fig. 1, is. the cup or chamber for holding the oil, and which may be constructed of any desired shape and capacity, and of any material suitable for the purpose. B is the stem and screw by which it is attached to the machine. From the neck or upper part of the cup projects the injection pipe 0, and from each side of the lower part or foot project the eduction pipes D D, fig. 3, to which reference will hereafter be made. To this cup is closely fittedthe plug E, fig. 2. A vertical section of the same is shown in fig. 3, in which figure it will be seen that the plug is not seated through the entire length of the cup, but at the upper and lower ends only, whereas the middle section is enclosed in or surrounded bythechamber F. It will also be'seen that the plug is not hollow through its entire length, but that the middle section, enclosed by the chamber F, is solid; hence the upper and lower ends of the'plugs G and H only are hollow or tubular, and which is put in communication with the chamber by means .of the holes or ports I and J, which pass through the diameters of the plug, thus bringing them in a like position on each side,

The manner of charging the cup with oil is as follows: It is poured into the saucer K, which is seen to surround the throat of the cup, and from which it enters the, hollow part of the plug'G through the holef, a corresponding hole being made in the throat, and which is brought in relation to that in the plug by turning it for that purpose. From the plug it flows through the ports I and B into the chamber F.

To the cduction pipes D D fig. 3', are attached conducting pipes, which lead off one to each valve at the end of the cylinder. The induction steam pipe 0, 1, is connected to the boiler or steam pipe, and from which the steam is received for blowing the oil into the cylinder on openingthe ports for that purpose.

The cup, on being thus properly connected and charged with oil, the practical application of the same to the valves by means of the cup is as follows: Forillustration, it is supposed that the valve to be oiled is at the right of fig. 3; then, on turning thehandle L to the position shown in said figure, which it willbe remarked is in the direction of the conducting pipe D, the oil will pass from the chamber through the port J down the hollow of the plug, and out of the port e through the eduction pipe D to the valve at the right, above referred to. At the same time steam will be inducted into the chamber through the pipe C, .which is now in-relation with the port a, which passes through the diameter of the plug; thus, whileone side of-theport is open, or in relation to the pipe, the other is closed. By this it will be evident that the steam will immediately descend to the t'op'oi' the oil, and by its pressure force the oil-out through the lower end of the plug, thence into the cylinder and valves, on turning the plug, so as to bring the handle in the opposite direction, or rather, in line with the direction of the pipe D. The port e will then be turned and brought in relation tothe pipe D leading to the left end of the cylinder, and thus closing the pipe D for the time. So also is the port a reversed. The opposite side of the same is broughtinrelation to the steam pipe C, through which the steam cnters the chamber as before, and drives the oil out through the port e along the pipe D to the valves, (is it did in the former case, and so, or as often as the plug may be turned, the steam enters at the top of the plug and drives the oil out at the bottom. On bringing the handle so that it .willstand at right angles with the eduction pipes, or in line reversely' with the pipe C, the ports a and e will be closed, thus shutting oil the steam from fth e chamber and oil from. the cylinder, which will then open the vents or air-holes g for the escape of the residual steam from the chamber. It at the some time opens-the hole f, communicatingwit'h the saucer K, and by which the cham her is charged with oil, in the some manner as above said.

This-cup can be constructed singly, or rather with single ports, for th s purpose of oiling one valve, &c.,

enly, and still rctain'tlle same principle of tho i nduction of the s team arid oil, and the eduction of the same fo the valves, tlius making it alike applicable to all pu use of steam, as the case may be.

rposes of oiling 'stemiL-ialves;journals, &; c., with or withgut the What I claim as my improvement, and desire to seeure by Letters Patent, is The plug E, provideu l with ports' I, J, and e, ports a and \"ent-lxoles g, as arranged, and in' combination with the cub A, fox-the purpose and in tllemanner set forth.
